Hi All, I have run into a problem I wanted to run by you all....I have a heater blower fan that won't run (1987 mera)...I have checked fuse, blower motor, relays...and today I finally worked back to the blower fan switch only to discover no power there at all. The ground 201 seems fine....so I am guessing I have a bad wire from the fuse block to the switch itself. I just wanted to check to see if anyone had any other ideas before I start looking to run a new wire. thanks

If HTR A/C Fuse has 12V on the Brown Wire
But not at the Blower Switch tab 'E'
You have an open Brown wire from the fuse block to the switch....

FYI
HTR A/C Fuse feeds three brown wires:
*Heat Blower Switch
*A/C Power Relay
*A/C Control Head

The Heat Blower Switch schematic shows one brown wire without any breaks from the fuse block to the switch
